A SEX predator who assaulted a young woman in a secluded park at knifepoint two months ago may have struck again, detectives revealed today.

The latest victim was accosted near Heartlands Hospital in Bordesley Green, Birmingham, and frogmarched into an alleyway where she was molested.

The attack, at 7.30pm on Wednesday, only ended when the attacker's mobile phone rang and he ran off allowing his terrified victim to alert police. Detectives said the incident bore striking similarities to another sex attack in the same area on December 14 last year.

Then, a woman waiting at a bus stop near the hospital after visiting a relative, was confronted by a man and threatened her with a knife.

He tied her hands with string before walking her past shops on Bordesley Green and then into a park tucked between houses. She was taken to a specific spot near a tree stump and sexually assaulted.

Today, police were investigating possible links between the two.

Det Insp Simon Vowles, from Stechford CID, said: "They are both very similar offences in the same area at roughly the same sort of time. The descriptions of the offender are also similar. But this latest victim was not tied up. We are now looking at whether these two incidents were linked."

The offender for the first offence was described as Asian, in his mid-to-late 20s, 5ft 9in tall, with a goatee beard. He wore a beanie hat, three-quarter-length leather jacket and black jogging bottoms.
